mount operations should be done in vendor init context, but their
complexity currently limits this. Add a TODO to make this reason

the signal was never delivered to the process. This caused at

ro.boot.* are from kernel cmdline, and kernel is usually owned by SoC
vendor or ODM.
So those properties should be allowed as action triggers of
vendor/odm init scripts.
Additionally the state of mediadrm (/system/bin/mediadrmserver) should
be used to operate the state of drm HAL.
So init.svc.mediadrm should be whitelisted as an action trigger as well.

vendor_init doesn't have permissions to read rootfs labeled files, but
needs to read /vendor_file_contexts to do restorecon correctly. This
file is a file_contexts file, so labeling it as such seems appropriate.

I'd be not doing this for a while since some of this code doesn't
compile on host and libinit previously did. But after realizing
the property_service.cpp (libinit) references symbols in init.cpp
(init) and seeing a new linker error crop up due to that, it's time to
make the fix.
My only hold out previously was that libinit compiled on host bionic
and some of init (builtins.cpp, etc) do not, however given that we
don't actually have host bionic support or host bionic init tests,
that isn't a good reason. We can and should mock out the libraries
that aren't available with host bionic when ready.
Test: build, unit tests, boot

Properties right now can take any format, but that makes it hard to
specify an API for these properties as Treble intends to do.
Therefore this change introduces the idea of property types, described below.
1) 'string' this is the default type and allows any property to be set.
2) 'bool' this allows only boolean values (true|false|1|0)
3) 'int' and 'uint' these allow signed and unsigned integer values
respectively.
4) 'double' this allows floating point numbers with double precision.
5) 'size' this allows for strings matching [0-9]+[gkm].
6) 'enum' this allows only a specific set of space deliminated values
to be set, e.g. 'enum allow these strings' only allows one of 'allow',
'these', or 'strings' to be set.
Bug: 70858511
Test: unit tests, test that properties are only set if their type matches

Currently init expands properties in arguments only when those
commands are run in a subcontext. This creates a hole where
properties that should not be accessible from a given subcontext of
init can be accessed when running a command in the main init
executable (for example `start`).
This change creates a callback in subcontext init that simply expands
and returns arguments back to the main init process, to ensure that
only those properties that a subcontext can access get expanded.

There is a 2s timeout for system property set that currently
uses boot_clock as its clock source. If the system goes to sleep
during a property set, it may erroneously cause the timeout to
be reached as boot_clock increments during sleep. This patch
changes from boot_clock to steady_clock to ignore time spent
asleep when determining this timeout.
bug: 71497234
Test: 1. System service process try to set a system property
with timeout 2s
2. At the same time, the system go into sleep mode more
than 2s
3. System property set will be ok.

Instead of requiring each process to parse the property contexts files
in libc initialization, this change has property_service parse these
files one into a serialized trie, which the property code in libc can
then directly interpret for mapping property names to their associated
SELinux context.

Init currently sets the SELinux context on a mkdir but not on
other operations. This patch modifies it to do so when creating
symlinks, writing to a file, or copying a file.
Test: Built, flashed, and booted. Added fake init entries and
verified that they received the proper SELinux context.

This change explicitly drops all inheritable capabilities (and, by
extension, ambient capabilities) when there are no explicit capabilities
being set by a service and the user is changed. This prevents Android
running in a container from accidentally granting extra capabilities to
services.
